Delphes 3.4.1 installation

[huayangs]

Hi,

I'm attempting to install Delphes, but whenever I use the make command, I get the following response:

/usr/bin/ld: cannot find -lImt
collect2: error: ld returned 1 exit status
Makefile:2158: recipe for target 'libDelphesNoFastJet.so' failed
make: *** [libDelphesNoFastJet.so] Error 1

I have ROOT 6.10/08 installed. I know that the structure of ROOT has been made some changes since version 6.08. However, I don't understand what causes this problem since the makefile uses root-config to get the path of ROOT's libraries. I'd really appreciate any help at all

Could you please run the following command and post its output here?

root-config --cflags --libs

Could you please run the following command and post its output here?

root-config --cflags --libs

The output is

-pthread -std=c++11 -m64 -I/usr/local//include/root -L/usr/local//lib/root -lCore -lImt -lRIO -lNet -lHist -lGraf -lGraf3d -lGpad -lTree -lTreePlayer -lRint -lPostscript -lMatrix -lPhysics -lMathCore -lThread -lMultiProc -pthread -lm -ldl -rdynamic

Thanks,

Thanks for the root-config output. So, as you can see -lImt is one of the ROOT libraries. If the linker can't find it, then probably there is something wrong with the ROOT installation. Could you check if you have /usr/local//lib/root/libImt.so installed?

Thanks for your help.

I found that some of the ROOT libraries were not compiled when I installed ROOT. I can figure it out by myself.
